Rogers genetic distance-based UPGMA phenograms for (a) 46 accessions of P. sativum subsp. sativum (sub-region or country of origin of each accession is given in front of the accession name); (b) 18 groups of accessions after grouping Ethiopian accessions into sub-region of origin; (c) seven groups of the accessions after grouping Ethiopian accessions into their regions of origin. Sub-regions in “B” that belong to the same region are connected to each other and to their corresponding region in “C” with arrows. The two Ethiopian accessions with unknown site of collections (32048 and 32776) were excluded in the case of “B” and “C”. Numbers in front of the branches are bootstrap values (only bootstrap values more than 50 % are shown)
